The power-on self-test state may refer to a state in which self-tests are performed on software and hardware of the steam ablation device after power-on, and in some examples, after the power-on self-test is passed, the steam ablation device may automatically enter a filling state.

During the monitoring, the steam ablation device can be checked for various predefined errors, and a corresponding process can also be performed based on the checking result.

The plurality of operating states may further include a configuration state in which software and hardware of the steam ablation apparatus are configured, and in the configuration state, relevant personnel may configure the software and hardware of the steam ablation apparatus through a human-computer interaction device or a data transmission medium.

The plurality of operation states may further include a setup state when steam ablation is performed, which may be understood as a state in which steam ablation time is manually set, an ablation start state, which may be understood as a state in which ablation is performed by starting steam ejection based on the set steam ablation time, and an ablation stop state, which may be understood as a state in which ablation is not performed by stopping.

In some examples, the above-mentioned operational states may be characterized using state information (e.g., a particular character or combination of characters) corresponding to the state. Specifically, the current state of the steam ablation device may be determined (switched or maintained) by setting a value at a specific value or a specific position (which may be understood as a value describing the current operation state of the steam ablation device) as state information of the corresponding state, for example, the state information describing the current operation state of the steam ablation device may be set as a standby state, thereby indicating that the steam ablation device is currently in or in a standby state.

In response to the above electrical self-test status and monitoring process, as shown in fig. 3 to 12 and 13, the embodiment of the present invention provides a test control method and a test controller of a steam ablation apparatus described later.

The specified water level according to the embodiment of the present invention may include at least one of: water level for preventing dry heating; a minimum normal water level; maximum normal water level; filling the top water level; the anti-dry heating water level is lower than the minimum normal water level, the minimum normal water level is lower than the maximum normal water level, and the maximum normal water level is lower than the top filling water level.

Wherein:

prevent dry combustion method water level can embody "prevent the basic demand of dry combustion method", for whether satisfy the judgement of preventing dry combustion method demand when steam generator heating, supplying water provides the basis, and then, the control that realizes based on this can help making the control result can match and satisfy and prevent the dry combustion method demand.

The minimum normal water level and the maximum normal water level can reflect the water demand when steam ablation and preparation work are normally carried out, and then heating and water supply control realized based on the water demand can help to enable the control result to be matched with the actual demand.

Referring to fig. 3, the inspection control method includes:

s201: monitoring the current water level, the current temperature, the current pressure and the current temperature in the steam generator; in some scenarios, only portions thereof may be monitored; what is specifically monitored can be arbitrarily configured based on requirements;

s202: and checking the steam ablation equipment according to the current water level and the current temperature in the generator.

As long as the software and hardware states of the steam ablation device are judged based on the monitored information and/or the processing corresponding to the judgment result is executed, an inspection can be realized. Further, the check can, for example, determine whether an error occurred, what kind of error occurred, and: corresponding peer-to-peer is implemented for errors.

In the above scheme, steam ablation equipment can be automatically checked based on the real current water level and the temperature in the current generator, and then the checking result can timely and accurately reflect the water level condition and the temperature condition in the steam generator.

Further, referring to fig. 4, the method may include:

s203: a current operating state of the steam ablation device is determined.

The process of step S203 may, for example, set a value describing the current operating state of the steam ablation device to corresponding state information.

For the power on self test state, step S203 may be, for example, when the steam ablation device is triggered to be powered on, determining that the current operation state of the steam ablation device is described as the power on self test state.

Regarding the filling state, the implementation of step S203 may be, for example, after the power-on self-test is passed, determining that the current operation state of the steam ablation device is the filling state;

for the preheating state, the implementation of step S203 may be, for example, when the steam ablation device is detected to meet the requirement of preheating while in the filling state, determining that the current operating state of the steam ablation device is the preheating state, where the detection of meeting the requirement of preheating may be, for example: detecting that the current water level is higher than or equal to the minimum normal water level;

for the standby state, the implementation of step S203 may be, for example, when detecting that the steam ablation device satisfies the standby requirement while in the preheating state, determining that the current operation state of the steam ablation device is in the standby state, where detecting that the standby requirement is satisfied may be, for example: detecting that the temperature in the generator is higher than the disinfection temperature and the water level is higher than the maximum normal water level;

for the ablation preparation state, the implementation of step S203 may be, for example, when the steam ablation device is in a standby state, and when it is detected that the steam ablation device satisfies the requirement of steam ablation, determining that the current operation state of the steam ablation device is in the standby state, where it is detected that the steam ablation device satisfies the requirement of steam ablation, specifically, for example: detecting that the disinfection process is completed and the current water level is higher than or equal to the maximum normal water level;

with respect to the setting state, the implementation of step S203 may be, for example, determining that the current operating state is the setting state in response to an operation to set a steam ablation time;

for the start state, the implementation of step S203 may be understood as detecting that the steam ablation device is blowing (or starting to blow), determining that the current operating state is the start state;

for the ablation stop state, the implementation of step S203 may be understood as detecting that the steam ablation device stops blowing after blowing, and determining that the current operation state is the ablation stop state.

The above is merely an example of step S203, but is not limited to the above.

Please refer to fig. 4, which illustrates an inspection control process when the current operation state is the power-on self-test state.

Referring to fig. 4, step S202 specifically includes:

s2021: whether the steam ablation equipment is in a power-on self-test state or not; further executing the subsequent steps in the power-on self-test state under the condition of judging yes;

s2022: whether the current water level is higher than or equal to a specified minimum normal water level:

s2023: whether the temperature in the current generator is lower than a specified first temperature threshold;

s2024: whether the control device has acquired an emergency stop feedback signal.

When the current water level is higher than or equal to the specified minimum normal water level and the current temperature in the generator is lower than the specified first temperature threshold, executing step S2025: controlling the steam ablation device to enter a shutdown operation state, wherein the steam ablation device entering the shutdown operation state can discharge water in the steam generator when the current water level is higher than or equal to an anti-dry heating water level, and the anti-dry heating water level is lower than the minimum normal water level.

The first temperature threshold is associated with a lower temperature limit of the temperature in the generator when the steam generator is heated, for example, the temperature in the generator needs to reach a certain range after heating in normal operation, which may be any specified temperature, and in one example, the first temperature threshold may be 95 degrees.

In a further aspect, step S2025 may further include, before the step, that:

s2024: whether the control device has acquired the emergency stop feedback signal;

the case of judging no can be understood as: determining that the control device has not acquired the emergency stop feedback signal.

If the emergency stop feedback signal is acquired, corresponding information can be fed back to the outside, and at the moment, the operator can choose to process in other modes without directly entering the shutdown state.

In one embodiment, referring to fig. 4, the inspection control method further includes:

when the steam ablation device is in the power-on self-test state, executing step S204: checking whether the steam ablation device is in error according to a plurality of specified events;

the plurality of specified events includes at least one of:

whether the display device is powered on;

whether the temperature monitoring device is normally connected with the control device or not is judged; the temperature monitoring device comprises a temperature monitoring device in the generator and a steam temperature monitoring device;

In addition to the self-test events designed for the steam ablation device above, the self-test of the control device to its own inherent hardware and software may be included, which may be accomplished using any existing or improved self-test means in the art. For example: if the control device adopts a singlechip, the control device can be realized based on a self-checking program of the singlechip.

In addition, if any one of the above event check results is that the steam ablation device fails (for example, the display device is not powered on, the display device is not in normal communication with the control device, the pressure monitoring device is not in normal connection with the control device, the temperature monitoring device is not in normal connection with the control device, the power supply voltage of the power supply is not in a set voltage allowable range, and a treatment timer in the control device cannot accurately time the external steam ablation of the steam ablation device), it is determined that an unrecoverable error occurs.

The unrecoverable error related to the embodiment of the present invention may be understood as an error unrecoverable when the steam ablation device is operating, and is defined as an error of the unrecoverable error, which may be because the influence range of the error is relatively large, for example, processing under multiple states may be related to, or because the error is checked and solved only when the operation is stopped, or may be because the risk caused by the error is relatively high; correspondingly, a recoverable error is understood to be an error which can also be recovered in the case of a steam ablation device which has not stopped working. By feeding back the information of the error type externally, the operator can be helped to judge whether to intervene to solve the error and in what way.

In one example, when the current water level is higher than or equal to the minimum normal water level, the current temperature in the generator is higher than or equal to the first temperature threshold, the control device does not acquire the emergency stop feedback signal, and no error is detected in step S204 (meanwhile, no error is detected by the control device, such as a single chip microcomputer), the power-on self-test may be considered to be passed.

Referring to fig. 5, the inspection control process is illustrated in a first target operation state, wherein the first target operation state is understood to be at least a part of the operation state of the steam generator after the preheating is completed, such as an ablation preparation state, a standby state, a setup state, an ablation stop state, and the like.

Referring to fig. 5, step S202 specifically includes:

s2026: whether the steam ablation device is in a first target operating state;

while in the first target operating state, step S2027 may be performed: and checking whether the steam ablation equipment has recoverable errors or not according to the current water level and the temperature in the current generator.

In a further embodiment, referring to fig. 6, step S2027 may include:

s20271: whether the temperature in the current generator exceeds a specified second temperature threshold;

s20272: whether the current water level is lower than a specified dry burning prevention water level or not;

if the temperature in the current generator does not exceed the second temperature threshold and the current water level is lower than the dry-heating prevention water level, step S20273 may be executed: determining that the recoverable error has occurred for the steam ablation device.

The second temperature threshold is associated with an upper temperature limit that the temperature in the generator needs to reach when the steam generator is heated, such as the upper temperature limit itself, or any temperature obtained based on the upper temperature limit, and in one example, the second temperature threshold may be 105 degrees.

In the above scheme, if an error that the temperature in the generator is lower than the upper temperature limit and the water level is lower occurs, the error can be determined as a recoverable error, and the corresponding error type is accurately defined, so that a basis is provided for repairing subsequent errors.

Referring to fig. 7, when in the first target operation state, the following steps may be further performed:

s2028: and checking whether an unrecoverable error occurs in the steam generating equipment or not according to the current temperature in the generator and the current pressure.

In a further aspect, step S2028 may include:

and checking whether the unrecoverable error occurs in the steam ablation equipment or not according to the measured relation between the current temperature in the generator and the current pressure and the set standard relation.

In one embodiment, referring to fig. 8, the inspection control method may further include:

s205: whether the steam ablation device is in a second target operating state;

while in the second target operating state, step S206 may be performed: checking whether the steam ablation equipment has errors or not according to the connection state of the water outlet connector.

The second target operation state is at least a part of the plurality of operation states of the steam ablation device, in which the steam ablation device needs to be drained, and may be, for example, one of a filling state, a preheating state, an ablation preparation state, an ablation stop state, and a shutdown operation state.

In order to ensure the accuracy of the check, it may be checked whether the duration of the water outlet connector which is not externally connected exceeds a threshold (e.g. 1 second), and if so, an error may be considered to have occurred (the error may be understood as a recoverable error).

s207: whether the steam ablation device is in a third target operating state;

while in the third target operating state, step S208 may be performed: checking whether an error occurs in the steam ablation device according to a connection state of a water inlet connector of the steam ablation device.

The third target operation state is at least a partial operation state of a plurality of operation states of the steam ablation device, in which water is required to be supplied to the steam generator, and may be, for example, one of a filling state, a preheating state, an ablation preparation state, and an ablation stop state.

In order to guarantee the accuracy of the check, whether the duration of the water inlet connector which is not externally connected exceeds a threshold (for example, 1 second) can be checked, and if the duration of the water inlet connector which is not externally connected exceeds the threshold, an error can be considered to occur (the error can be understood as a recoverable error).

In one embodiment, referring to fig. 10, the inspection control method further includes:

s209: monitoring whether water accessed to the steam ablation equipment from a water source is sterile water or not, and determining corresponding duration time information, wherein the duration time represents the duration time of monitoring the sterile water or not;

s210: checking whether the steam ablation device has an error according to the duration information.

In a specific example, step S210 may compare, for example, whether the duration information exceeds a set threshold (for example, 60 seconds), and if so, it may be considered that an error (specifically, a recoverable error) has occurred.

Further, the above processing procedure may be performed in the third target operation state, that is, the processing performed in the case where the determination of step S207 is yes.

In one embodiment, referring to fig. 11, the inspection control method further includes:

s211: and checking whether the steam ablation equipment has errors or not according to the temperature in the current generator and the temperature safety threshold.

For example, an error (e.g., a non-recoverable error) may be determined to have occurred when the temperature within the current generator is above a temperature safety threshold.

In one embodiment, referring to fig. 12, the inspection control method further includes:

s213: checking whether the steam ablation equipment has errors or not according to the current pressure and the pressure safety threshold value.

For example, an error (e.g., an unrecoverable error) may be determined to have occurred when the current pressure is above a pressure safety threshold.

The detection and comparison of the pressure safety threshold and the temperature safety threshold may be performed in a specific state or may be performed in all states. For example, the heating can be performed when heating is needed, for example: a pre-heat state, a standby state, an ablation ready state, a set state, an ablation off state, and the like.

Optionally, the inspection control method further includes:

s212: checking whether the steam ablation equipment has errors or not according to the current steam temperature.

The fourth target operating state is at least a portion of the plurality of operating states of the steam ablation device that have met steam ablation requirements, such as an ablation ready state, a setup state, and so forth.

The steam temperature threshold is associated with the steam temperature required for performing steam ablation, and may, for example, be matched to the minimum steam temperature required for performing steam ablation, the actual position of the monitored steam being different, and the steam temperature threshold employed may be different, for example, if the current steam temperature monitored is the temperature of the steam returned to the condensing device: the steam temperature threshold may be, for example, 110 degrees, and when the monitored current steam temperature is lower than 110 degrees, an error (specifically, an unrecoverable error) may be considered to have occurred, and at this time, the temperature of the steam delivered by the steam generator may be higher than the actually monitored current steam temperature, but the current steam temperature may still be indicative of the temperature of the steam delivered by the steam generator.

All the above processes of controlling according to the specified water level (for example, the dry-heating prevention water level) are not limited to the processing mode of directly comparing the specified water level with the current water level, the processing mode of participating in calculation according to the difference value, the ratio and the like of the current water level and the specified water level, and the processing mode of participating in calculation according to the average value of the current water level within a certain time are not excluded, and the same is true for controlling according to the temperature and the pressure. Any variations do not depart from the scope of the embodiments of the present invention.
